A small book, published in April 2013 with 20th anniversary issue of the Jazz & Tzaz magazine. It includes a record of the Greek jazz discography by year (title, artist, company and album code), as well as four very good introductory articles: 1. Jazz in the interwar period (Manolis Seiragakis) 2. The period 1940-1970 (Phontas Troussas) 3. The '70s and' 80s (George Charonitis) and 4. From 1990 until today (Kornilios Diamantopoulos). As the author of the book later wrote "A monumental edition for our ... jazz + jazz discography, which will now be a guide for anyone who wants to go further". The book was indeed and still remains a valuable guide to Jazz Library.
